To all IUILUIH/ it ntag concern.-

Be it known that 1, WILLIAM M. PRICE, a citizen of the United States, residing at Oshkosh, in the county of Vinnebago and State of Wisconsin, have invented new and useful Improvements in Pipe-Holders, of which the following is a specification.

My invention relates to pipe-holders, and has for an object the provision of a pipeholder embodying two curved pivoted jaws adapted to automatically engage the pipe to be held.

A further object of the invention is to provide a pipe-holder with curved pivoted jaws, the pipe-engaging faces of which are grooved, so as to adjust themselves to grasp pipes of different diameters.

A further object of the invention is to provide a pipe-holder either of whose grooved jaws is formed with concaved semicylindrical surfaces adapted to permit of fiat engagement of said jaw with the pipe being held, while the grooved surface of the other jaw is corrugated, so as to permit of its firmly gripping the pipe and binding it tightly against one of the flat surfaces of the opposite jaw.

A still further object of the invention is to provide a pipe-holder of the class described with grooved surfaces, said grooves being tapered, so as to permit of their engaging ipes of different diameters.

With these and other objects in view the invention consists of certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter more fully described and claimed.

In the drawings, Figure 1 is a view in side elevation of one embodiment of my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a cross-section taken on the line 3 3 of Fig. 2 looking in the direction of the arrow. Fig. 4 is a cross-section taken on the line 3 3 of Fig. 2, but looking in the direction opposite that taken in Fig. 3. Fig. 5 is a detail section of one of the pipe-engaging jaws, taken on line 2 2 of Fig. 2 looking in the direction of the arrow.

Like characters of reference designate corresponding parts throughout the several figures of the drawings.

Referring to the drawings, 10 indicates the base or carriage as a whole, which carriage may be of any preferred construction. The carriage shown consists of a rectangular bottom 11, cut away, as at 12, to permit of the ready introduction of the pipe to the pipe-gripping jaws, as will be hereinafter explained. Mounted upon the bottom 11 are upright supports 13, 14, and 15, the upright 13 extending the entire length of the bottom 11, while the upright 14 extends from one end of said bottom to where it is cut away at 12, and the upright 15 extends from the opposite end of said bottom to where it is cut away. Braces 16 and 17 connect uprights 13 and 14 and 13 and 15, respectively, to add strength to the device as a whole, and uprights 13 and 15 are so cut away, as at 18 18, as to permit of the free swinging of the operating T-shaped treadle 28 to be hereinafter described. The up rights are perforated, as at 19 19, to serve as bearings for the axles 20 and 21, upon which are pivoted the curved pipe-engaging aWs 22 and 23 now to be described.

Jaw -3 is of the same general conformation as its fellow jaw 22; but the groove 33 on its pipe-engaging surface is formed with concaved semicylindrical surfaces 31, 32, 33, and 34, which are adapted to flatly engage different sizes of pipe and hold. such pipe securely against downward vertical movement; The concaved semicylindrical surfaces are positioned at such an angle with respect to the pivotal point of the jaw 23 as to present an elongated contact-surface, which is adapted to snugly fit and contact throughout the entire surface thereof with various sizes of pipes being gripped. The weight of the jaws will automatically bring into position the particular sized concaved surface that is necessary for gripping any pipe that may be operated upon.

In use the operator by exerting pressure upon the treadle 28 directly or through one of the ends of the T portion of the treadle causes the jaw 22 to move about its axle, and in so moving the cogs of the gear 27 engage the cogs of the gear 26 and cause jaw 23 to simultaneously move about its axle, thus bringing the pipe-engaging surfaces of said jaws to their uppermost and Widest position. The'treadle 28 is preferably formed with a T or cross-arm on its outer end, as clearly seen in Fig. 2 of the drawings. The operator may operate the jaws either by directly exerting pressure on the end of the treadle or on one of the cross-arms or T portions of the outer end. If the pressure is exerted on one of the arms, the operator may operate the jaws from either side of the device, as the firmly by the appropriate perpendicular ofv jaw 23 and the proper and corresponding portion of the corrugated groove on jaw22= Itwilgl; readily be seen that with the pipe v engaged flatly-by one of the perpendiculars onjaw 23- and firmlypressed. thereagainst and clutched by the corrugations on the cooperating jaw 22 the pipewilljbe positively held against a downward movement.

Whilel have shown and described myin ventiom as embodying. specific features, it will be obvious that certain changes may be madein thedetails of construction and opera atiorr; without departing from the. spirit of my invention What 1 clairnlisf 1.
